DINING-TABLE. FAN.

SPECIFICATION forming part of Letters Patent No. 398,250, dated February19, 1889. Application filed Jul 13,1888. Serial No. 279,822 (No model.)

To all whom it may concern:

Be it known that 1, DAVID JAMES GREGORY, a citizen of the United States,residing at Scranton, in the county of Lackawanna and btatc ofPennsylvania, have invented certain new and useful Improvements inDining Table Fans; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the ('[COOIII panying' drawings, and to theletters and tigurcs of reference marked thereon, which Form a part ofthis specification.

This im'ention relates to fly-fans for dining or other tables, and hasfor its object the provision of a fan that can be readily operated bythe foot on atrcadlc within convenient reach, and which will be simple,compact, and efficient.

The improvement consists of the details of construction, whichhereinafter will be more fully described and claimed, and shown in theannexed drawings, in which Figure 1 is a perspective view of a table,showing my invention applied thereto; and Fig. 2, a sectional detailabout on the line X X of Fig. 1.

The table A is of ordinary construction, and is shown simply toillustrate the application of myinvention. The standard l3, having thetan-operating devices on its upper end, is socured to the table at itslower end, and is preferably tubular to form a case for the rod a. Theblock I) is secured to theplate 1), provided at the upper end of thestamlard, and has the uprights fastened to its sides. The shaft I) isjournaled in the brackets (t on the block I), and its ends projectthrough openings in the u nig'hts (I and have the fans E ad j ustal )lymounted thereon. lever F, keyed on the shaft I), has its horizontal armconnected with the rod (1 The vertical arm of the bell-crank lever D isslotted, and the cross-barf, that closes the outer end of the slot, isrounded. The shaft G is journaled in the ln'ackets g, secured to theuprights (1, and its ends are provided with fans E. This shaft isoperated from the shat't D by any suitable interposed connections or Theb ell-crank gearing, that shown being the arm I, which engages with thevertical arm of the bellcrank lever. This arm I is secured to the shaftG, and its lower end is bifurcated and embraces the end f of the leverF. The shaft 5 5 G is provided intermediate of its ends with the secondfan E which is double, being socured to the shaft by the set-screw 0',which passes through the arm I.

The fans E and -E' are constructed. alike, and are formed from sheetmaterial, which is cut to form the wings e e and the stem 6, the blankbeing sul)s quently bent to have the wings stand at an angle of aboutforty degrees and the stem 6 to form a tube which embraces the end ofthe shaft. The thumbscrcw 6 holds the fan adj ustably on the shaft. Therod a passes down through the table, and is connected to the treadle Jwhich is supported on the stand K, connected with the table by thebrackets j. The inner or lower end of the treadle is provided with theplate L, which is bent to bring its ends in different planes, and isprovided with pairs of brackets l and Z, which are disposed on oppositesides of the plate. The rod a is pivotally connected with the bracketsZ, and the treadle J is pivotally connected with the brackets Z. Thecoii-sprin M, mounted on the rod a and confined between the table andthe plate I 1t orccs the inner end of the treadlc down.

To operate the tans, th e person presses down on the trcadle,whicheffects an upward movement oi": the inner en d of the treadle and therod a. Thepressure beingremoved, the spring carries the treadle back toits normal position. This movement causes a "ibratoryinotion ofthebell-crank lever and a corresponding motion of the fans, which drivesoff the flies. go

It will be noticed that the plate L is pivotally connected with the endof the treadle J, to facilitate the operation of the latter beyond whatcould be obtained if the said treadle were rigid from its outer end tothe point of connection bet-ween. the said lever and the rod (1, as willbe readily con'i -irehemled.

Ilaving thus described my invention, what I claim, and desire to secureby Letters Patent,
